“…The strong agreement between results of assessments based on diatoms and those based on chironomids may reflect the tight coupling between benthic diatoms and chironomid grazers (Maasri et al 2008, Tarkowska-Kukuryk 2013. The data set used for these comparisons was small, and the association may be a by-product of 2 independent strong correlations with the underlying TP gradient, but the possibility of a functional link between the 2 groups suggests that the outcome of assessing both components is more than the sum of assessing 2 separately.…”

“…High chironomid grazing pressure may substantially reduce the biomass of periphytic algae (Jones and Sayer 2003;Tarkowska-Kukuryk 2013). For this reason, chironomid larvae may act as an important top-down regulator of periphyton biomass, and the removal of periphyton by grazing larvae may improve light conditions for macrophytes.…”

Four submerged macrophytes were analysed with their respective assemblages of chironomid and algal taxa. Studies were made bimonthly, from January to November, in a shallow macrophyte-dominated lake. The periphytic algal community was represented by chlorophytes, diatoms and cyanobacteria; diatoms showed the highest relative abundance on the macrophyte species during the study. Algal biomass was affected by the season, and in January the highest values were found on Stratiotes aloides L., Potamogeton lucens L., Myriophyllum spicatum L.; in July on Chara aculeolata Kütz. The lowest algal biomass, on most of the macrophytes studied, was found in September. Larvae of Dicrotendipes sp., Diplocladius cultriger Kieffer, Endochironomus albipennis gr., Endochironomus impar (Walker), Glyptotendipes sp. and Paratanytarsus austriacus Kieffer were dominant within the chironomid community. The spatial distribution of chironomids between macrophytes species was related to periphytic algae biomass and certain environmental variables (temperature, water transparency, biomass of chlorophytes and diatoms). Analysis of chironomid diet and the results of canonical correspondence analysis confirmed this relationship. The strongest chironomid-algae relationships were observed on S. aloides and P. lucens.

“…Grazing pressure may be very important biotic factor shaping epiphyton assemblages (Abe et al, 2007;Guariento et al, 2010;Tarkowska-Kukuryk, 2013). In the studied lakes, the pressure from fish grazing (with S. erythrophthalmus as the most significant species) could affect epiphytic algae, particularly in Lake Krzczeń, with the highest fish abundance.…”

“…Epiphytic algae are involved in primary productivity, nutrient cycling, and energy transfer in littoral food webs (Abe et al, 2007;Tarkowska-Kukuryk, 2013). They can decrease the growth and production of submerged macrophytes as they provide increased shading (Takashi et al, 2004).…”

-Epiphytic algae are an important group of organisms involved in primary productivity, nutrient cycling, and energy transfer in littoral food webs. However, multifactorial studies conducted on epiphyton on the same substrate across a spectrum of environmental parameters are very limited. Here, we present first complex field study on the role of abiotic and biotic factors in shaping the species richness, diversity, abundance, and biomass composition of epiphyton on common reed in four shallow lakes with different trophic status, water and fish management, and the abundance and structure of potential algal grazers: littoral crustaceans and fish. The obtained results revealed that the algal taxa richness was the lowest in the hypertrophic lake and the highest in the meso-eutrophic lake. Epiphyton abundance (predominated by pennate diatoms) and biomass were found to be the highest in eutrophic water bodies. Biomass consisted primarily of diatoms, but we found the seasonal predominance of filamentous Chlorophyta (in the eutrophic lakes) and Chlorophyceae (in the meso-eutrophic lake). Redundancy analysis (RDA) showed that the frequency of water level fluctuations was the most significant variable in the composition of epiphyton. RDA also revealed the importance of grazing pressure of fish. Thus, in hydrologically transformed lakes, man-made factors may be of great relevance in the development of epiphytic algae.Keywords: Epiphyton abundance / biomass / diversity / algal grazers / TSI index Résumé -Le rôle des facteurs environnementaux abiotiques et biotiques dans la formation de l'épiphyton sur le roseau commun dans les lacs tempérés peu profonds et modifiés sur le plan hydrologique. Les algues épiphytiques constituent un groupe important d'organismes impliqués dans la productivité primaire, le cycle des éléments nutritifs et le transfert d'énergie dans les réseaux trophiques littoraux. Toutefois, les études multifactorielles menées sur l'épiphyton sur le même substrat portant sur un éventail de paramètres environnementaux sont très limitées. Nous présentons ici une première étude de terrain complexe sur le rôle des facteurs abiotiques et biotiques dans la formation de la richesse, de la diversité, de l'abondance et de la composition de la biomasse de l'épiphyton sur les roseaux communs dans quatre lacs peu profonds ayant différents statuts trophiques, gestion de l'eau et des poissons, ainsi que l'abondance et la structure des brouteurs d'algues potentiels: crustacés littoraux et poissons. Les résultats obtenus ont révélé que la richesse taxonomique des algues était la plus faible dans le lac hyper-eutrophe et la plus élevée dans le lac méso-eutrophe. L'abondance de l'épiphyton (dominée par les diatomées pennées) et la biomasse étaient les plus élevées dans les plans d'eau eutrophes. La biomasse se composait principalement de diatomées, mais nous avons trouvé la dominance saisonnière de Chlorophyta filamenteux (dans les lacs eutrophes) et de Chlorophyceae (dans le lac méso-eutrophique).
